How do we cope with small minded people?
See, there are so many types of people in this world. How many people do you know who have for no reason become your enemies? Your good friends have become your enemies? Isn't it?
Similarly, so many people who were unknown to us have helped us at some point of time. We may not have done anything for them, but they helped us out.
So friends or enemies are all a cause of our karmas. If our time is wrong, friends can become enemies, and if our time is right, enemies can turn into friends.
